Technical Audit Of Terminal Metering

This is a specialized service to evaluate the performance of metering systems, in complying with the requirements as laid down in the American Petroleum Institute (API) Measurement Standards.

Oil and Gas Metering System

The major components of a Technical Audit are;

  • An evaluation of the condition and design of each metering system with regards to Electronic Condition as per API Standard.

  • Verification of throughout, calculations for Gross Measured Volume Standard Volume Validation of any other Computer Constants and or functions.

  • Calibration checks on Temperature and Pressure Instrumentation.

  • Check on-line sample analysis Procedures and function test auto sampler.

  • Establishing flow curves for meters over the flow range for linearity and repeatability.

  • Verification of Proving calculation and examination of current prover loop calibration Certificate, checking current base volume is in use and correct defect switch pair is selected.

    Examination of internal condition of Prover.

  • Prove that all critical valves in system are bubble tight when closed under normal operating condition; function check associated leak detector system.

    Calibration of instrumentation can also be conducted in the course of the exercise to reduce errors and improve overall measurement uncertainty.
